1. Customer’s responsibility
- If the IO is clear, then this indicates there is a blockage in the service connection on the private property and the IO may be used to provide access for a plumber to clear the blockage.
- If sewage flows out of the IO, this indicates a blockage from outside the property boundary and TasWater should be called to attend.
If IO is unknown/inaccessible
- The property owner is responsible to locate the IO or engage a registered plumber/drainer to install one. This may require contacting local councils to consult drainage plans. Property drainage plans are not kept or maintained by TasWater.
- The first IO inside the property boundary shall be raised to ground surface level as an inspection shaft forming part of the private system achieving compliance with current standards. The owner is responsible for the cost of work performed on the private system and in all cases responsible for the cost of raising the first IO to the surface.
2. Plumber’s responsibility
- may inspect TasWater infrastructure using the IO for the purpose of ascertaining whether a blockage has occurred downstream of the IO (i.e. within the private property owners area of responsibility – private system)
- are not permitted to open or otherwise access TasWater infrastructure, such as manholes, without TasWater authorisation
Responsibility Regarding Sewer Blockages & Failures
- are prohibited from performing any construction or maintenance work, including the clearing of blockages on TasWater infrastructure, including the clearing of blockages located within TasWater sewer infrastructure without TasWater authorisation; and must contact TasWater on 13 6992 upon diagnosing a blockage within TasWater’s infrastructure.
Clearing blockage (private system)
- In all cases involving hand or machine rodding the plumber must work from the downstream end of the line in an upstream direction and prevent the material causing the blockage entering the TasWater system.
If determined the blockage is in the TasWater system
If it is agreed the blockage is in the TasWater system and TasWater authorises the work, the plumbers invoice must be sent to TasWater and be fully itemised to include:
- The TasWater contact person,
- Plant & material,
- Any fees payable.
3. TasWater’s responsibility
- Sending staff to the blockage to clear it, or
- Authorising the plumber to clear the blockage.
